To all whom it may concern:

Be it known that I, Mrcrmnrl H. SHANLEY, a citizen of the United States of America, residing at Granbury, in the county of Hood and State of Texas, have invented certain new and useful Improvements in Ventilators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of referenccinarked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in combined flues and ventilators; and it consists in the construction and combination of the parts, as will be here inafter fully set forth, and specifically pointed out in the claims.

In the accompanying drawings,which illustrate my invention, Figure 1 is a side view of a combined flue and ventilator constructed in accordance with my invention. Fig. 2 is a vertical section. Fig. 3 is a transverse section taken through the line a: :v of Fig. 2. F1 g. i is a detail perspective view.

My improved flue and ventilator is applied to the roof of a building, and extends through the same to the apartment which it is desired to ventilate, so that the same can be employed during the winter months as a smoke-exit passage and during the summer as a ventilatorpassage compartment.

A refers to the outer casing, which extends through the roof and above the same, and downward into the compartment. This outer casing is provided centrally with a flue, B, which extends from the compartment or room, preferably near the ceiling, to a suitable distanee above the roof, and a transverse coverplate, I), is secured to the outer casing, A, and through a central opening therein the central flue, 3, passes. Above the plate l3,to the easing A, is attached a suitable cap, 0, of ornamental configuration, which is provided, near its upper part, with a cover portion, 0, between whieh and the lower portion, 0, is a space, through whichim pure airfrom the apartment may pass in summer or smoke in winter. The lower portion of the cap 0 has near its base a series of perforations, 0, through which air may pass, so as to create an upward draft above the flue through the exit-opening be' neath the cover-plate G.

The space D, between the central fine, B, and the outer wall or casing, may, if desirable, be formed in two independent compartments, or may consist of a single compartment, as desired.

The outer casing, A, near its upper end, is provided on its four sides with shields or screens (1, and beneath the same are located openings E, said screens or curved plates d being located above said openings, so as to prevent rain or snow entering therein. Beneath the openingsE the outer casing, A, is provided with hinges 6, one of the leaves of said hinges being secured. thereto, while the opposite leaf is attached to the under side of the funnels F, said funnels being fully illustrated in Fig. 4 of the accompanying drawings. The funnels have attached near their inner ends staples f, to which flexible connections are secured, said flexible connections extending therefrom downwardly through the compartment 1) and into the chamber, the 1owor ends being provided with rings or knobs.

If desirable, the compartment 1) may have located therein tubes G, through which the flexible connections or cords y will pass, these tubes also serving as conduits for the air from the interior of the building, and these tubes. when desired, may extend under the outer compartment, A, to suitable points within the room. \Vhcn the tubes G are not employed, the out-er casing, A, has perforations, through which the air may pass.

\Vhcn it is desired to ventilate a compartment, the operation of my invention is as follows: The stove-pipe from the heating apparatus is connected to the central tube, B,which forms the smoke-exit passage, and when i t desired to have air in the room for ventilating purposes the funnel on the side from which the wind is blowing is raised and held in an elevated position by drawing upon and securing the flexible connection which causes the air to enter the tube through which the flexible connection passes into the room. The funncls are of suflicient weight to drop automatically, and are raised and held in a raised position by the flexible connections hereinbefore described.

with a central flue, funnels F, hinged to theouter casing and provided with flexible connections for elevating the same, and means for conducting the air downward from said funnels, substantially as shown, and for the purpose set forth.

2. In a combined flue and ventilator, an outer casing,A,having screens or shields d at tached thereto, openings located under said shields, and hinged funnels adapted to be elevated from within the building, and a central flue through the outer casing, the parts being organized substantially as shown, and for the purpose set forth.

3. In a combined flue and ventilator,'a11 outer casing provided with a central fine and tube, G, located between said flue and casing, and funnels F, hinged to the outer portion of the casing, so as to lead into the tube G, and means for elevating said funnel from the interior of the building, substantially as shown, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses. r
